I was thinking about this earlier. I know from my own research that some of them are evil in that they dont seem to have much respect for life.

I also know that some of the alien races and kind and helpful.

I find it interesting that in almost every movie that features aliens they are portrayed as evil attackers. There arent many that depict them in a different light.

Why is that? Are the elite training us to hate all alien races via hollywood entertainment? I wonder.
